Natron Energy presented its battery cell back in 2021. Now the market launch is set to begin on a large scale. The performance data of the new type of battery is very remarkable.

Nuclear fusion is to be made more controllable with an elaborate measuring instrument. However, the expense and the rather simple measurement parameter involved also show that there is still a long way to go to achieve economic viability.

QLED, OLED, now PeLED. The new pixels do not promise better picture quality, but an all-round solution for smart and mobile devices. The functional principle is surprisingly simple, but makes numerous sensors superfluous.

Electronic waste has become a growing problem, and researchers at the University of Washington may just have found a solution. The team has showcased new circuit boards that are almost 100% recyclable. These new PCBs (printed circuit boards) are made of vitrimers that turn into a jelly-like substance during recycling.

A smartwatch can do more than just collect data. Thanks to training with patient data, AI recognizes dangerous heartbeat disturbances before they occur and provides time for intervention.

How do you transmit information with quantum entanglements whose exact behavior is barely understood? Certainly not in bits and bytes or via LAN cable. But perhaps with light.

Some tasks are better solved as a team. 4.5 million Borderlands 3 players worldwide are a team. And they were able to decode the genetic material of bacteria and their evolution better than current computer programs.

Debate It has been just over 20 years since Facebook first launched as a Harvard university project. In that time, a significant number of other platforms have launched including TikTok, Twitter (X), Snapchat, Instagram and more. But do these platforms still contribute something to society or do they cause more harm than good?

Enormous conductivity, scalable manufacturing process and reliable charging. With optimized production, readily available raw materials and solid electrolyte, solid sodium batteries could soon be practically usable - with record-breaking ion conductivity.

A ship powered by ABB's Dynafins is expected to be feasible by 2026. A study conducted by ABB together with Ritz Carlton revealed that the propulsion system, which is modeled on the animal kingdom, requires up to 20% less energy and, above all, runs quietly.

All problems would be eliminated in one fell swoop: A newly developed battery technology uses the cheap and widely available sodium, has a practicable energy density and charges with almost no waiting time.

Tiny devices such as contact and temperature sensors or for weather measurement and automation are spreading rapidly. The power supply requires cables or batteries, which a new type of energy cell could change.

With 1.15 billion neurons, the Intel Hala Point is the world's largest neuromorphic system. Taking advantage of the Loihi 2 processor and deployed at Sandia National Laboratories, this system's capacity is similar to that of an owl brain and will be used to solve computing problems in device physics as well as computer science.

HD Atlas has been retired. But Boston Dynamics is sending a completely new Atlas onto the test field without further ado. It no longer "bleeds" hydraulic fluid and is intended to help Hyundai with its cars.

It is the perfect demonstration of extremely lightweight solar modules with gigantic energy density: a multicopter is fitted with only solar cells, which then supply enough power for the small aircraft to take off as usual.

Can robots bleed? Yes, one could be forgiven for thinking so when watching Boston Dynamics' new farewell video of HD Atlas. Viewers could also be forgiven for also feeling pain upon seeing the many trips, stumbles and falls.

It's about lithium-ion batteries in smartphones and notebooks. A simple change to the charging protocol doubles the possible charging cycles. However, the path to this realization proved difficult.

Solar cells in orbit could permanently supply huge amounts of electricity around the clock, regardless of the weather and without using up land surface. Now it's all about the technical realization and financial feasibility of electricity from space. Two concepts are in the starting blocks.

It will be the size of a three-room apartment, fits in a shoebox when folded and could speed up future missions enormously. Sailing with solar wind could break several speed records.

A surprising discovery made in the data retrieved by the European Space Agency’s Gaia mission is the BH3 stellar black hole, located just 2,000 light years from Earth. No less than 33 times the size of the sun, BH3 is the largest of its kind in the Milky Way and the second one (by size) to be spotted so far.

The James Webb Telescope is the gift that keeps on giving for scientists. Rather than confirming what we already thought we understood about the universe, it is challenging everything at the heart of what is known and accepted as the standard cosmological model.

A geostationary satellite at an altitude of 36,000 kilometers (22,000 miles) had the best view of the solar eclipse on April 8. No clouds blocked the view here. On the contrary.

Transistor open or closed, 0 or 1, that's what a microchip is based on. With a newly developed two-dimensional magnet, a completely different circuit enters the playing field, which has a lot to offer, especially in terms of efficiency.

Photographing a golf ball from 24 kilometers away or searching the universe for dark matter: With over 3 billion pixels, a lot is possible, even if the camera has not become very handy.

This gigantic value was achieved on a normal fiber optic connection, which usually only provides a fraction of this bandwidth. And the technical innovations for performance are also limited.

Wind and solar energy provide a lot of electricity, but never consistently and everywhere. A third renewable energy source - hydrovoltaics - aims to do just that, using surprisingly simple means.

The Chūō Shinkansen will not be able to run in 2027. In some places, construction work has not even begun. Shizuoka Prefecture, which is resisting the construction of the high-speed line, is particularly affected.

Getting rid of CO2 once it has been released is very complex. Even plants have a hard time with it. So why not simply produce useful substances from it?

Thermonuclear explosions hurl sometimes exotic elements into space at high speed. This teaches us a lot about the physics behind them and the universe, except that observing them is difficult.

A third of all CO2 emissions worldwide end up in the oceans. The only problem is that the absorption capacity is decreasing and the water in the oceans is also acidifying. Part of the solution could be CCS from water.
